Abstract:</p>
<p>Optical
interferometry is a widely used technique for ultra-precision distance
measurements in many areas of science and technology, enabling fundamental
physical experiments, such as the hunt for gravitational waves, and
underpinning important industrial technologies, such as semiconductor
fabrication. My particular research deals with the question on how multiple
measurements at different points can be taken simultaneously using only one
instrument. This can be achieved by appropriately modulating the optical
wavelength of the laser used and a very simple way to perform these
measurements is the signal processing technique developed during my PhD thesis
project. A key advantage of this approach is that it reduces the number of
optical components needed and instead shifts complexity of the measurements
into the electronics, potentially enabling very cost-effective measurements. As
this technology is very new many potential applications still remain
unexplored.</p>
